1. A vehicle comprising:
- a processor configured todetermine current and limit handling conditions based on an acceleration parameter that has upper and lower thresholds defining an interval within which the parameter may fall without initiating stability control,determine a margin between the current and limit handling conditions based on a normalized difference between the parameter and one of the thresholds, anddelay received interface tasks from being executed based on the margin.

Abstract
A vehicle'"'"'s dynamic handling state, driver inputs to the vehicle, etc. may be examined to determine one or more measures of driver workload. Driver interface tasks may then be delayed and/or prevented from executing based on the driver workload so as to not increase the driver workload. Alternatively, driver interface tasks may be scheduled for execution based on the driver workload and caused to execute according to the schedule, for example, to minimize the impact the executing driver interface tasks have on driver workload.

5. A vehicle comprising:
a processor configured to determine current and limit handling conditions based on a plurality of vehicle handling parameters that each have upper and lower thresholds defining an interval within which the parameter may fall without initiating electronic stability control, anti-lock braking or traction control, wherein the plurality includes vehicle speed, vehicle yaw rate, vehicle lateral acceleration, vehicle longitudinal acceleration or steering wheel angle, determine, for each of the parameters, a normalized difference between the parameter and at least one of the parameter'"'"'s upper and lower thresholds to determine a margin between the current and limit handling conditions, determine a driver workload based on the margin, schedule received interface tasks for execution based on the driver workload, and cause the scheduled interface tasks to be executed. - View Dependent Claims (6)

7. A method for managing driver interface tasks comprising:
by a processor, determining a margin between current and limit handling conditions based on a plurality of vehicle handling parameters that each have upper and lower thresholds defining an interval within which the parameter may fall without initiating electronic stability control, anti-lock braking or traction control, wherein the plurality includes vehicle speed, vehicle yaw rate, vehicle lateral acceleration, vehicle longitudinal acceleration or steering wheel angle, determining a driver workload based on a margin between the current and limit handling conditions, wherein the margin is based on a normalized difference, for each of the parameters, between the parameter and one of the parameter'"'"'s upper and lower thresholds, and selectively delaying or preventing received interface tasks from being executed based on the driver workload. - View Dependent Claims (8, 9, 10)
